GREEN LAKE, Wis. (WTAQ) - The Green Lake County District Attorney says an Ohio man convicted of killing fish has failed to fulfill his part of the plea agreement.

Timothy Smith was convicted of three violations of DNR ordinances in a fish kill in November 2009. Smith had been hired to kill carp, but his nets also killed 3,000 walleye, northern pike and catfish. The DA wants to revoke that agreement.

A hearing has reportedly been scheduled for next month to determine what the next step should be. Smith was to pay $300 per month to start covering more than $22,000 in fines, assessments and court costs.

The District Attorney filed his motion last Friday because Smith has missed making the required payments.
